If you can create a nano-sized QR code, it will be a measure against information leakage. This is because in order to disclose information, it is necessary to have Scaffold DNA and Staple DNA suitable for constructing a structure, and also a device and technique for observing the fabricated structure are also required. In addition, you can erase the information by swallowing the sample etc. Because it is made entirely from DNA, it does not harm the human body. Also, since the end of the DNA double helix is present on all sides of the DNA QR code of this time, it is possible to bind the DNA origami to each other. By doing so, we will be able to increase the amount of information than the one we made this time.
